After transmission, all error bits are removed - with the exception of
device errors. Device errors have to be removed by means of the
ESC @ control command, by activating the init-signal of the Centronics
interface, or by switching the printer off and on.
Remarks:
Bit 0,
device error
Device errors are reported when mechanical malfunctions in the printer
occur, which are recognized by the microprogram to have exceeded
the timeouts. Possible device errors are:
-
Interference in carrier movement, recognized by timeout of con-
secutive carrier pulses.
-
Interference in cutter movement, recognized by timeout of the
cutter disc revolutions and/or a change of signal at its home
sensor.
Device error message in BEETLE/60 mode occurs only when a cut
command was sent to the printer.
Bit 1,
cover error
In the EPSON-TM930 and ND69 modes, Bit 1 always equals 0. A cover
error is reported when a print job cannot be carried out with open cover.
Bit 2,
user error
User error is reported when no document has been inserted within the
time specified by ESC f. User errors are reported in the BEETLE/60 mode
when there is no paper on a station (printstop sensor active) and when
a line feed on the receipt station shall be executed after an interference
on the cutter has occured.
Bit 3
memory error
Memory error is reported when an error occurs during the memory test
(RAM and ROM).
